|C4 Depollution System Faulty / Engine Management Light on|
|C4 2.0 HDi has the following error codes: P2408 Fuel Cap Sensor / Switch Circuit, P0470 Exhaust Pressure Sensor A Circuit & P1429 Electric Air Pump Primary failure.
Having driven and reset the code a couple of times the error: P2408 Fuel Cap Sensor / Switch Circuit keeps coming back and if I leave it long enough the P0470 Exhaust Pressure Sensor A Circuit also returns.
I have been told by a dealer there was an issue with the original Exhaust Pressure Sensor. You now replace it with a different sensor, additional pipe and bracket for the pipe.
Replaced the Exhaust Pressure Sensor and yes it did need a new bracket. This was in fact located under the Battery mount (Which needs to be removed) in the enguine bay.
I did not replace the hoses however as to remove the clips from the exaust end would seem to need the removal of the exaust.
All it took was a litttle turning/twisting of the hoses in place and they attached quite comfortably to the new sensor.
